One end of this: spring The caml? will be hereinafter.referredito bears against the flipper edgeoi the i anm:29i ml) will lift the operating lever 33 and cause the working dog 31toforce the arm 29 upward, and as the inner end of the lever 22 is connected with this arm 29 throughthe rod 40, the inner end of this presser arm lever will be likewise moved upward to force the arm 21 into clamping engagement with the sole s. The spring 41 acts to compensate for excess movement of the presser arm lever 22, and pressure of this arm upon the sole may be regulated by adjusting the tension of the spring.

Continued rotation of the cam 17 will move the operating lever 33 pivotally downward, the dog 25 serving to hold the presser arm lever againstdownward movement until the operating lever 33 reaches its limit of clownward movement, whereupon the offset portion 36 of the lever 33 strikes the arm 38 of the dog 25 and releases the dog from engagement with the lever 22. This operation is repeated during the rotary movement of the cam 18 so that the presser arm lever- 22 is alternately moved into and out of gripi ping position.

Extending outward from the table 10 is a guide which accommodates a horizontally movable slide 46. This slide has pivotally attached thereto as shown at 47, one end of a hand lever 48. Secured transversely to this lever is an arcuate block 49 which is en gaged by the outer end of a lever 50, the said lever being provided in its under face with a groove 51 for'that purpose. The lever is a pivotally mounted as shown at 52 and the inner end of this lever carries a roller 53 which operates in a cam groove 54 which extends around the periphery of the slide cam 17 V 7 When the cam 17 is rotated, the arm 50 will be moved upon its pivot 52 and through the engagement of the outerend of this arm with the arcuate block 49, the slide 46 will be reciprocated.

Extending upwardly from one end of the slide 46 is a lmife guideblock 55. This block is provided with a vertically extending-dovetailed guide gr'oove'56 which accommodates a knife block 57 Removably secured withinthefupper enduof this block is a transversely angular knife 58 which operates through a' similarly shaped opening 59 provided in the extension 21 of the arm 20. One end of this opening is of suflicient size to permit the knife to movehorizontally in a direction transverse of the block 20, this movement being coextensive with the movement of the slide 46.

The block 57 is toothed along one edge as shown at 60 and these teeth are engaged by the teeth 61 at one end of the lever 62. This lever is pivotally mounted as at 63 and carries a laterally extending roller 64 which operates in a cam groove 65 provided in the lifting cam 18.

v When the cam 18 is rotated, the lever 62 will be moved pivotally to alternately raise and lower the knife block 57;

In the operation of the machine, the toe of the shoe is adjusted to the arm 20 with the extended portion of the sole extending over the upper edge of this arm, the particular point of contact between the toe of the shoe and the arm 20 depending upon the amount to be cut from the sole." In other words, as the outer face of the arm 20 is inclined with respect to the position of the knife 58, the position of the toe along this inclined edge will determine the amount of the sole which extends over the slot 59. As the shaft 13 rotates, the presser arm will be moved downward into gripping engagement with the sole as previously described, whereupon, the arm 62 will operate to force the knife 58 upward through the sole and will make an L- shaped cut in the edge of the sole as shown at a in Figure 7 of the drawings. At this pointfthe presser arm will release the sole and the slide 46 will be moved to advance the sole a distance equal to the length of the cut. The presser arm will again grip the'sole and-the knife, through the movement of the slide 46, will return to its initial position andwill be again moved upward for the next cut 6. A step by step movement will thus be imparted to the sole and the operation will be repeated at each step.

In addition, the invention provides a substantially L-shaped arm 65 which is pivotally mounted as shown at 66. The outer end of this arm 65 has removably secured thereto as shown at 67, a channeling knife 68. A spring 69 forces this knife into the sole, so that as the sole is'moved step bystep, a channel will be cut in the underface of the sole. The spring 69 has one end secured to the arm 19 and its opposite'end secured to the arm 65' in such a way that when the arm 65 is moved uponits pivot 66, the knife 68 will be either held in position to engage the sole, or will be maintainedin elevated position.

This invention is susceptible of various changes in its form, proportions and minor" details of construction and the right is herein reserved to make such changes as properly fallwithin the scope of the appended claims. Having described the invention what is claimed is 1. In a rough rounding machine, a stationary sole engaging arm, a movable presser arm adapted to engage and. clamp the sole upon the stationary arm, a vertically and horizontally movable rounding knife, means to operate the knife to alternately cut and move the sole, and means tooperate the presser arm to clamp the sole in cutting position, said presser arm operating means including a pivotally mounted presser arm lever having the presser arm extending rigidly therefrom, a pivotally mounted controlling arm, means connecting thevl-ever and piv otally mounted arm to resist relative doWn- Ward movement, a pivotally mounted operating lever, means to move said operating lever pivotally, means carried by the operating lever and engaging the controllingarm to move the lever pivotally in one direction, and means controlled by the operating lever to hold the presser arm lever against accidental retrograde movement.

-2. In a rough rounding machine, atable, a stationary sole engaging arm supported n thereby, a presser arm lever supported for pivotal movement above the table, a presser arm disposed above the stationaryarm and rigid with said lever and cooperating with the stationary arm to gripthe sole, a rotary drive shaft, a slide cam and a lift cam carried 7 by said shaft, means to operate the presser arm to intermittently grip and release the sole including a pivoted operating lever actuated by the slide cam, a horizontally disposed reciprocatory slide, a vertically disposed knife block guide rigid with the slide, a block movable vertically in the guide, a knife carried by the block, a lever to move the block vertically in opposite directions to cut the sole actuated from the lift cam, and means actuated from the slide cam to reciprocate the slide to move the knife horizontally'and impart a step by step movement to the sole in timed relation to operation of the presser arm. 7 o
